Gorilla tape will probably do. I would not attempt to change it, since it's already there, but do keep an eye on it and if it does start to come off, then go to plan "B".
FYI, I never travel with water in my fresh tank for the very reason you just described. There's a lot of weight in those tanks, and then you add all the bumping up and down and water movement inside the tank, and ... well ... I've just never had confidence to travel with full tanks. Moving around the campground, no problem, 5, 10 mph, but at highway speeds, and highway bumps, and highway chuck holes and railroad tracks and such ... nah, not comfortable at all.
For longer trips, we take a separate 6 gallon jug of water for on-the road usage, and keep the tanks as empty as possible.
X2. I travel with all 3 holding tanks empty, except a minimal amount in the fresh water tank for usage on the road. I refill at my next location. I do understand that those who are traveling to a dry camping location may need to travel with water.
